I think this hasn't been update since 2017, and most of it is from 2016.<p>I pretty much only use javascript for d3, and I put it down for a while. Recently I decided to do something with d3 v5.0[1], and got confused about the state of ES6 modules. Has anyone gotten rollup to work with d3? Is it possible to just use ES6 modules natively in the browser if you don't care about older browsers?<p>My other issue was with async/await. It seems like when I used async await on a locally hosted csv file, it could take between 1 and 2 seconds to load. For my colleague sometimes minutes. When I switched to d3 v4.0 and the old callback approach, it loaded instantly, even for my colleague. What gives?<p>[1] <a href="https://github.com/d3/d3/blob/master/CHANGES.md" rel="nofollow">https://github.com/d3/d3/blob/master/CHANGES.md</a>
